Instructions

1.

Preheat your oven to 350°F (175°C). Grease and line a 13x18-inch sheet pan with parchment paper.

2.

In a medium bowl, whisk together flour, baking powder, and salt.

3.

In a large bowl, beat butter and sugar until light and fluffy (about 3–4 minutes).

4.

Add eggs one at a time, beating well after each addition. Mix in vanilla extract.

5.

Add dry ingredients to the wet mixture in three parts, alternating with the milk. Begin and end with dry ingredients. Mix until just combined—do not overmix.

6.

Pour batter into prepared pan and smooth the top.

7.

Bake for 30–35 minutes, or until a toothpick inserted in the center comes out clean.

8.

Let cake cool completely in the pan on a wire rack.

9.

For the frosting, beat butter on medium speed until creamy (about 2 minutes). Gradually add powdered sugar, beating well. Mix in vanilla and enough milk or cream to reach desired consistency.

10.

Divide frosting: color portions as needed for base, borders, and piping Class of 2026.

11.

Spread a smooth layer of frosting over the cooled cake. Pipe borders and Class of 2026 using a piping bag fitted with writing and star tips. Add sprinkles or edible decorations as desired.

12.

Refrigerate cake for 30 minutes before serving to set the frosting.

Zusatztipps für die Zubereitung

Für intensive Farben in der Buttercreme verwenden Sie am besten Gel-Lebensmittelfarben. Sie können die Dekoration ganz individuell an die Schulfarben und den Stil des Absolventen anpassen. Die Butter sollte für cremige Konsistenz unbedingt Raumtemperatur haben, und lassen Sie dem Kuchen ausreichend Zeit zum vollständigen Auskühlen vor dem Dekorieren.

Varianten und Anpassungen

Für eine Schokoladenvariante ersetzen Sie ½ Tasse Mehl durch ungesüßtes Kakaopulver. Wer möchte, kann die Buttercreme mit Marmorierung oder verschiedenen Spritztüllen gestalten. Dekorieren Sie zusätzlich mit essbarem Glitzer, farbigem Zucker oder besonderen Streuseln für einen individuellen Look.

Serviervorschläge

Servieren Sie das Kuchenstück zu erfrischender Limonade oder Fruchtpunsch für den perfekten Festgenuss. Der Blechkuchen ist ideal für Buffets und lässt sich gut vorbereiten. Reststücke einfach abgedeckt im Kühlschrank lagern und später genießen.
